SKIN-STRETCHING FRAME.

Specification of Letters Patent.

Application filed August 2,V 1919. Serial No. 314,834.

To ZZZ 'whom it may concern,

Be it known that l, HARRY W. THOMP- SON. a citizen of the United States, residing vat Philadelphia, in the county of Philadel- These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which l Figure 1 is a front elevation of my improved frame showing thereon a skin in stretched condition,

Fig. 2 is a top plan view of Fig. 1, Fig. 3 is a rear elevation ot Fig. 1,y F ig. 4 is an end view of Fig. 3, Fig. 5 is a sectional elevation taken on the line .5-5 of Fig. 1,

F ig. 6 is a perspective view of certain of the elements of my improved frame, and

Fig. 7 is a perspective view of my improved frame. M

Referring to the drawing`s5 my improve trame includes two uprights' 8 and 9. Each of these uprights is made up of front and rear strips 10 and 11 which are spaced apart between their ends by blocks 12 and are joined together at their tops and bottoms by transverse upper and lower beams 13 and 11i. Each of the beams 13 and 111 is made up ot' front and rear strips 15 and 16 which are spaced apart between their ends by blocks 17. The strips 15 of the upper and lower beams extend between and are joined to the strips 10 and 11 of the uprights 8 and 9. The strip 15 of the beam 13 has end portions 18 which entend beyond the up.- rights 8 and 9 and provide means whereby the frame can be suspended in an uprightV position by any suitable Voverhead means Patented Novle, ieee.

l(not illustrated). Each of the beams 13 and 11i have two rows of holes 19 and 20; the 'holes being arranged in staggered formation and so that the holes in the strips the strips 16 so that pins 21` can be inserted through any of the holes so as to entend across the space 22 between the strips 15 and 16 in each ot the beams 13 and 14.

ln like manner the strips 10 and 11 or 15 are directly in register with the holes in each of the uprights Sand 9 have two rows of holes 23 and 2st; said holes `being arranged in staggered formation, the holes of the strips 10 being in register with the holes in the strips 11 so that pins 25 can be inserted therethrough and entend across the space 26 between the front and rear strips lOand 11. A board 27, which will hereinafter be termeda neclr board, has its opposite ends 28 slidable vertically in the spaces 26 below the blocks 12.r opposite ends 3Q secured within the spaces 26 above' the blocks 12 and directly below the upper beam 13, said board beingphereafter termed the belly board.

Two upright shank boards 31 and-32 have their upper and lower ends respectively slidable within the spaces 22 at opposite sides ofthe blocls 17. These shank boards A second board 29 has its are normally held from falling' through the spaces 22 by the provision of stop blocks 83 which slidably rest upon the upper edges of the strips 16 oit the lower beam 14. lThe K shank boards 31 are each provided with shank bay extensions 34e; the front surfaces 35 being flush or in the same plane with the front surface 36 of the neck board 27 and belly board 29.

By the above arrangement it will be noted that the shank boards are slidable transversely to the direction in which the neclr board is slidable and that the shanlr boards are slidable in a different plane than the plane of movement orthe neck board. However, the surfaces 35 of the shank bay exteni sions slide in the same plane as that of the surfaces 36 of t le neclr board 27. Furthermore, the front surface 37 of the belly board 29 is in the plane of the surface 36 oft the neck board 2'? and the surfaces 35 of the. shank bay extensions 3ft.

ln stretching a slain, such for example as the skin shown at 38 in Fig. 1, the belly lower beams and uprights in a staggered f Vau Vportion 39 is secured by nails, pins or other suitable means such as shown at 10 to the belly board 29. rlhe shank portions i1 of the skin areseeured in similar manner to the shank bay extensions and the neck portion 42 is similarly secured to the neck board 27. The shank boards 31 and 32 can be moved apart and the neck board 27' can be moved downwardly by any suitable means so as to stretch the skin and after said shank` boards. and neck board have been moved, they can be secured, in the positions into which they have been moved, by, inserting the pins 21 and in their respective holes immediately adjacent the top edge of thel neck board and the inner edges of the shank boards, as clearly shown in Fig. 7

By arranging the holes in the upper` and formation as. illustrated, it is possible to place the holes aV suiiicient distance apart to insure sufficient strength of material, but

Vat the same time a very small adjustment o can be secured since the pins can beV inserted in the holes which are nearest to the above mentioned edges of the shank and neck boards irrespective of the row of holes in which the pins arel inserted.

From the foregoing description it will be understood that the spaces 22 and 26 provide slid'eways respectively for the shank boards and neck board and the blocks 12 andV 17 form a separating means to insurea freedom of movement of said shank and neck boards and at the same time the blocks 1 but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what Y described. Y ,1

I claim as new and desire to secure by Letters Patent is :n

1. A stretching device of the character described including a frame and transversely extending boards slidably connected Vto said frame and movable in directions transversely to each other, said boards having portions overlapping each other and other portions providing surfaces in the same plane whereby a skin can be secured against said surfaces in their plane; substantially as described.

2. A stretching frame including uprights and beams, said upriglits and beams being made up of strips spaced apart to provide slidewayscertain of the strips of said beams extending between and being secured to the strips of saidy uprights; transversely extend ing boards movable Awithin said slideways; and means for securing Said boards in various positions within said slideways, certain of Said boards having extensions providing surfaces included in Va plane including an outer surface of another of said boards so that material can be secured against saidV surfaces their plane; substantially as described.

3. A stretching frame including uprights and beams, saiduprights and beams being made up of strips spaced apart to provide slideways, Certain lof the strips of said beams extending between and being secured to the strips of said uprights; and a vertically extending board and a horizontallyV extending board respectively slidable within the slide-v ways of said beams and uprights, said vertically slidable board having a stop block thereon for engagement with one of Vsaid beams forv pre'venting'the downward movement of said' vertical boa-rd; substantially as In testimony whereof :have Signed my name to this specification in the presence of two subscribing witnesses.
